Rihanna Cancels Houston Concert

Rihanna has bailed on yet another stop on her Diamonds world tour. This time, the 'Stay' songstress canceled her concert for tonight (April 15) in Houston.

The Associated Press reports that the Bajan superstar is sitting it out "as a result of illness." Live Nation said that members of the Rihanna Navy should hold on to their tickets, which would be honored at a rescheduled date.

Rihanna was previously too sick to perform shows in Baltimore and Boston, citing laryngitis for the missed performances. Earlier this week, she was spotted smoking up and having a grand old time with her beau, Chris Brown, so let's hope she gets well soon and that whatever she has isn't contagious -- otherwise Team Breezy may be disappointed too.
